I used to tell people there IS a surefire way to do it, even if the fedgov is involved, at least for a while. It involves what I posted above as well as storing your computer and disguise in a storage unit somewhere. But where it gets complicated nowadays is that there are cameras simply EVERYWHERE. So they can backtrack you from the location via ring cameras, etc., possibly all the way to the storage unit.
Of course, once they track you to the location you use, they can simply stake it out, which is why you’d need to use a different location every time. Maybe riding a bike there from a parking spot where you know there is no camera surveillance nearby.
Anyway, it can be done. You just have to be anal about it. And even then there are no guarantees. And no, I’ve not actually done this. I just like to think about ways to thwart “the system”. Way back in 1972 a workmate asked me why I was always thinking of ways to rip off the company. I told him it was just fun to find security risks. Looking back in hindsight, I probably should have gone into security.
First, buy a USED computer from a Goodwill or thrift shop or a repair shop. Pay cash, no credit card..................
Don’t forget to turn off your phone and leave it at home.
